# How to contribute #
We'd love to accept your patches and contributions to this project. There are
a just a few small guidelines you need to follow.
## Contributor License Agreement ##
Contributions to any Google project must be accompanied by a Contributor
License Agreement. This is not a copyright **assignment**, it simply gives
Google permission to use and redistribute your contributions as part of the
project.
* If you are an individual writing original source code and you're sure you
own the intellectual property, then you'll need to sign an [individual
CLA][].
* If you work for a company that wants to allow you to contribute your work,
then you'll need to sign a [corporate CLA][].
You generally only need to submit a CLA once, so if you've already submitted
one (even if it was for a different project), you probably don't need to do it
again.
[individual CLA]: https://developers.google.com/open-source/cla/individual
[corporate CLA]: https://developers.google.com/open-source/cla/corporate
Once your CLA is submitted (or if you already submitted one for
another Google project), make a commit adding yourself to the
[AUTHORS][] and [CONTRIBUTORS][] files. This commit can be part
of your first [pull request][].
[AUTHORS]: AUTHORS
[CONTRIBUTORS]: CONTRIBUTORS
## Submitting a patch ##
1. It's generally best to start by opening a new issue describing the bug or
feature you're intending to fix. Even if you think it's relatively minor,
it's helpful to know what people are working on. Mention in the initial
issue that you are planning to work on that bug or feature so that it can
be assigned to you.
1. Follow the normal process of [forking][] the project, and setup a new
branch to work in. It's important that each group of changes be done in
separate branches in order to ensure that a pull request only includes the
commits related to that bug or feature.
1. Do your best to have [well-formed commit messages][] for each change.
This provides consistency throughout the project, and ensures that commit
messages are able to be formatted properly by various git tools.
1. Finally, push the commits to your fork and submit a [pull request][].
[forking]: https://help.github.com/articles/fork-a-repo
[well-formed commit messages]: http://tbaggery.com/2008/04/19/a-note-about-git-commit-messages.html

the Work and Derivative Works thereof.
"Contribution" shall mean any work of authorship, including
the original version of the Work and any modifications or additions
to that Work or Derivative Works thereof, that is intentionally
submitted to Licensor for inclusion in the Work by the copyright owner

3. Grant of Patent License. Subject to the terms and conditions of
this License, each Contributor hereby grants to You a perpetual,
worldwide, non-exclusive, no-charge, royalty-free, irrevocable
(except as stated in this section) patent license to make, have made,
use, offer to sell, sell, import, and otherwise transfer the Work,
where such license applies only to those patent claims licensable
by such Contributor that are necessarily infringed by their
Contribution(s) alone or by combination of their Contribution(s)
with the Work to which such Contribution(s) was submitted. If You
institute patent litigation against any entity (including a
cross-claim or counterclaim in a lawsuit) alleging that the Work
or a Contribution incorporated within the Work constitutes direct
or contributory patent infringement, then any patent licenses
granted to You under this License for that Work shall terminate
as of the date such litigation is filed.
4. Redistribution. You may reproduce and distribute copies of the
Work or Derivative Works thereof in any medium, with or without
modifications, and in Source or Object form, provided that You
meet the following conditions:
(a) You must give any other recipients of the Work or
Derivative Works a copy of this License; and
(b) You must cause any modified files to carry prominent notices
stating that You changed the files; and
(c) You must retain, in the Source form of any Derivative Works
that You distribute, all copyright, patent, trademark, and
attribution notices from the Source form of the Work,
excluding those notices that do not pertain to any part of
the Derivative Works; and
(d) If the Work includes a "NOTICE" text file as part of its
distribution, then any Derivative Works that You distribute must
include a readable copy of the attribution notices contained
within such NOTICE file, excluding those notices that do not
pertain to any part of the Derivative Works, in at least one
of the following places: within a NOTICE text file distributed
as part of the Derivative Works; within the Source form or
documentation, if provided along with the Derivative Works; or,
within a display generated by the Derivative Works, if and
wherever such third-party notices normally appear. The contents
of the NOTICE file are for informational purposes only and
do not modify the License. You may add Your own attribution
notices within Derivative Works that You distribute, alongside
or as an addendum to the NOTICE text from the Work, provided
that such additional attribution notices cannot be construed
as modifying the License.
You may add Your own copyright statement to Your modifications and
may provide additional or different license terms and conditions
for use, reproduction, or distribution of Your modifications, or
for any such Derivative Works as a whole, provided Your use,
reproduction, and distribution of the Work otherwise complies with
the conditions stated in this License.
5. Submission of Contributions. Unless You explicitly state otherwise,
any Contribution intentionally submitted for inclusion in the Work
by You to the Licensor shall be under the terms and conditions of
this License, without any additional terms or conditions.
Notwithstanding the above, nothing herein shall supersede or modify
the terms of any separate license agreement you may have executed
with Licensor regarding such Contributions.
6. Trademarks. This License does not grant permission to use the trade

except as required for reasonable and customary use in describing the
origin of the Work and reproducing the content of the NOTICE file.
7. Disclaimer of Warranty. Unless required by applicable law or
agreed to in writing, Licensor provides the Work (and each
Contributor provides its Contributions) on an "AS IS" BASIS,
WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
implied, including, without limitation, any warranties or conditions
of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
PARTICULAR PURPOSE. You are solely responsible for determining the

whether in tort (including negligence), contract, or otherwise,
unless required by applicable law (such as deliberate and grossly
negligent acts) or agreed to in writing, shall any Contributor be
liable to You for damages, including any direct, indirect, special,
incidental, or consequential damages of any character arising as a
result of this License or out of the use or inability to use the
Work (including but not limited to damages for loss of goodwill,
work stoppage, computer failure or malfunction, or any and all
other commercial damages or losses), even if such Contributor
has been advised of the possibility of such damages.
9. Accepting Warranty or Additional Liability. While redistributing
the Work or Derivative Works thereof, You may choose to offer,
and charge a fee for, acceptance of support, warranty, indemnity,
or other liability obligations and/or rights consistent with this
License. However, in accepting such obligations, You may act only
on Your own behalf and on Your sole responsibility, not on behalf
of any other Contributor, and only if You agree to indemnify,
defend, and hold each Contributor harmless for any liability
incurred by, or claims asserted against, such Contributor by reason
of your accepting any such warranty or additional liability.

# Build tool dependency policy
To ensure the broadest compatibility when building the benchmark library, but
still allow forward progress, we require any build tooling to be available for:
* Debian stable AND
* The last two Ubuntu LTS releases AND
Currently, this means using build tool versions that are available for Ubuntu
16.04 (Xenial), Ubuntu 18.04 (Bionic), and Debian stretch.
_Note, [travis](.travis.yml) runs under Ubuntu 14.04 (Trusty) for linux builds._
## cmake
The current supported version is cmake 3.5.1 as of 2018-06-06.
_Note, this version is also available for Ubuntu 14.04, the previous Ubuntu LTS
release, as `cmake3`._

# Assembly Tests
The Benchmark library provides a number of functions whose primary
purpose in to affect assembly generation, including `DoNotOptimize`
and `ClobberMemory`. In addition there are other functions,
such as `KeepRunning`, for which generating good assembly is paramount.
For these functions it's important to have tests that verify the
correctness and quality of the implementation. This requires testing
the code generated by the compiler.
This document describes how the Benchmark library tests compiler output,
as well as how to properly write new tests.
## Anatomy of a Test
Writing a test has two steps:
* Write the code you want to generate assembly for.
* Add `// CHECK` lines to match against the verified assembly.
Example:
```c++
// CHECK-LABEL: test_add:
extern "C" int test_add() {
extern int ExternInt;
return ExternInt + 1;
// CHECK: movl ExternInt(%rip), %eax
// CHECK: addl %eax
// CHECK: ret
}
```
#### LLVM Filecheck
[LLVM's Filecheck](https://llvm.org/docs/CommandGuide/FileCheck.html)
is used to test the generated assembly against the `// CHECK` lines
specified in the tests source file. Please see the documentation
linked above for information on how to write `CHECK` directives.
#### Tips and Tricks:
* Tests should match the minimal amount of output required to establish
correctness. `CHECK` directives don't have to match on the exact next line
after the previous match, so tests should omit checks for unimportant
bits of assembly. ([`CHECK-NEXT`](https://llvm.org/docs/CommandGuide/FileCheck.html#the-check-next-directive)
can be used to ensure a match occurs exactly after the previous match).
* The tests are compiled with `-O3 -g0`. So we're only testing the
optimized output.
* The assembly output is further cleaned up using `tools/strip_asm.py`.
This removes comments, assembler directives, and unused labels before
the test is run.
* The generated and stripped assembly file for a test is output under
`<build-directory>/test/<test-name>.s`
* Filecheck supports using [`CHECK` prefixes](https://llvm.org/docs/CommandGuide/FileCheck.html#cmdoption-check-prefixes)
to specify lines that should only match in certain situations.
The Benchmark tests use `CHECK-CLANG` and `CHECK-GNU` for lines that
are only expected to match Clang or GCC's output respectively. Normal
`CHECK` lines match against all compilers. (Note: `CHECK-NOT` and
`CHECK-LABEL` are NOT prefixes. They are versions of non-prefixed
`CHECK` lines)
* Use `extern "C"` to disable name mangling for specific functions. This
makes them easier to name in the `CHECK` lines.
## Problems Writing Portable Tests
Writing tests which check the code generated by a compiler are
inherently non-portable. Different compilers and even different compiler
versions may generate entirely different code. The Benchmark tests
must tolerate this.
LLVM Filecheck provides a number of mechanisms to help write
"more portable" tests; including [matching using regular expressions](https://llvm.org/docs/CommandGuide/FileCheck.html#filecheck-pattern-matching-syntax),
allowing the creation of [named variables](https://llvm.org/docs/CommandGuide/FileCheck.html#filecheck-variables)
for later matching, and [checking non-sequential matches](https://llvm.org/docs/CommandGuide/FileCheck.html#the-check-dag-directive).
#### Capturing Variables
For example, say GCC stores a variable in a register but Clang stores
it in memory. To write a test that tolerates both cases we "capture"
the destination of the store, and then use the captured expression
to write the remainder of the test.
```c++
// CHECK-LABEL: test_div_no_op_into_shr:
extern "C" void test_div_no_op_into_shr(int value) {
int divisor = 2;
benchmark::DoNotOptimize(divisor); // hide the value from the optimizer
return value / divisor;
// CHECK: movl $2, [[DEST:.*]]
// CHECK: idivl [[DEST]]
// CHECK: ret

#### Using Regular Expressions to Match Differing Output
Often tests require testing assembly lines which may subtly differ
between compilers or compiler versions. A common example of this
is matching stack frame addresses. In this case regular expressions
can be used to match the differing bits of output. For example:
```c++
int ExternInt;
struct Point { int x, y, z; };
// CHECK-LABEL: test_store_point:
extern "C" void test_store_point() {
Point p{ExternInt, ExternInt, ExternInt};
benchmark::DoNotOptimize(p);
// CHECK: movl ExternInt(%rip), %eax
// CHECK: movl %eax, -{{[0-9]+}}(%rsp)
// CHECK: movl %eax, -{{[0-9]+}}(%rsp)
// CHECK: movl %eax, -{{[0-9]+}}(%rsp)
// CHECK: ret
}
```
## Current Requirements and Limitations
The tests require Filecheck to be installed along the `PATH` of the
build machine. Otherwise the tests will be disabled.
Additionally, as mentioned in the previous section, codegen tests are
inherently non-portable. Currently the tests are limited to:
* x86_64 targets.
* Compiled with GCC or Clang
Further work could be done, at least on a limited basis, to extend the
tests to other architectures and compilers (using `CHECK` prefixes).
Furthermore, the tests fail for builds which specify additional flags
that modify code generation, including `--coverage` or `-fsanitize=`.

# User-Requested Performance Counters
When running benchmarks, the user may choose to request collection of
performance counters. This may be useful in investigation scenarios - narrowing
down the cause of a regression; or verifying that the underlying cause of a
performance improvement matches expectations.
This feature is available if:
* The benchmark is run on an architecture featuring a Performance Monitoring
Unit (PMU),
* The benchmark is compiled with support for collecting counters. Currently,
this requires [libpfm](http://perfmon2.sourceforge.net/) be available at build
time
The feature does not require modifying benchmark code. Counter collection is
handled at the boundaries where timer collection is also handled.
To opt-in:
* Install `libpfm4-dev`, e.g. `apt-get install libpfm4-dev`.
* Enable the cmake flag BENCHMARK_ENABLE_LIBPFM.
To use, pass a comma-separated list of counter names through the
`--benchmark_perf_counters` flag. The names are decoded through libpfm - meaning,
they are platform specific, but some (e.g. `CYCLES` or `INSTRUCTIONS`) are
mapped by libpfm to platform-specifics - see libpfm
[documentation](http://perfmon2.sourceforge.net/docs.html) for more details.
The counter values are reported back through the [User Counters](../README.md#custom-counters)
mechanism, meaning, they are available in all the formats (e.g. JSON) supported
by User Counters.

# Random Interleaving
[Random Interleaving](https://github.com/google/benchmark/issues/1051) is a
technique to lower run-to-run variance. It randomly interleaves repetitions of a
microbenchmark with repetitions from other microbenchmarks in the same benchmark
test. Data shows it is able to lower run-to-run variance by
[40%](https://github.com/google/benchmark/issues/1051) on average.
To use, you mainly need to set `--benchmark_enable_random_interleaving=true`,
and optionally specify non-zero repetition count `--benchmark_repetitions=9`
and optionally decrease the per-repetition time `--benchmark_min_time=0.1`.

# How to release
* Make sure you're on main and synced to HEAD
* Ensure the project builds and tests run (sanity check only, obviously)
* `parallel -j0 exec ::: test/*_test` can help ensure everything at least
passes
* Prepare release notes
* `git log $(git describe --abbrev=0 --tags)..HEAD` gives you the list of
commits between the last annotated tag and HEAD
* Pick the most interesting.
* Create one last commit that updates the version saved in `CMakeLists.txt` to the release version you're creating. (This version will be used if benchmark is installed from the archive you'll be creating in the next step.)
```
project (benchmark VERSION 1.5.3 LANGUAGES CXX)
```
* Create a release through github's interface
* Note this will create a lightweight tag.
* Update this to an annotated tag:
* `git pull --tags`
* `git tag -a -f <tag> <tag>`
* `git push --force origin`

# Benchmark Tools
## compare.py
The `compare.py` can be used to compare the result of benchmarks.
### Dependencies
The utility relies on the [scipy](https://www.scipy.org) package which can be installed using pip:
```bash
pip3 install -r requirements.txt
```
### Displaying aggregates only
The switch `-a` / `--display_aggregates_only` can be used to control the
displayment of the normal iterations vs the aggregates. When passed, it will
be passthrough to the benchmark binaries to be run, and will be accounted for
in the tool itself; only the aggregates will be displayed, but not normal runs.
It only affects the display, the separate runs will still be used to calculate
the U test.
### Modes of operation
There are three modes of operation:
1. Just compare two benchmarks
The program is invoked like:
``` bash
$ compare.py benchmarks <benchmark_baseline> <benchmark_contender> [benchmark options]...
```
Where `<benchmark_baseline>` and `<benchmark_contender>` either specify a benchmark executable file, or a JSON output file. The type of the input file is automatically detected. If a benchmark executable is specified then the benchmark is run to obtain the results. Otherwise the results are simply loaded from the output file.
`[benchmark options]` will be passed to the benchmarks invocations. They can be anything that binary accepts, be it either normal `--benchmark_*` parameters, or some custom parameters your binary takes.
Example output:
```
$ ./compare.py benchmarks ./a.out ./a.out

What it does is for the every benchmark from the first run it looks for the benchmark with exactly the same name in the second run, and then compares the results. If the names differ, the benchmark is omitted from the diff.
As you can note, the values in `Time` and `CPU` columns are calculated as `(new - old) / |old|`.
2. Compare two different filters of one benchmark
The program is invoked like:
``` bash
$ compare.py filters <benchmark> <filter_baseline> <filter_contender> [benchmark options]...
```
Where `<benchmark>` either specify a benchmark executable file, or a JSON output file. The type of the input file is automatically detected. If a benchmark executable is specified then the benchmark is run to obtain the results. Otherwise the results are simply loaded from the output file.
Where `<filter_baseline>` and `<filter_contender>` are the same regex filters that you would pass to the `[--benchmark_filter=<regex>]` parameter of the benchmark binary.
`[benchmark options]` will be passed to the benchmarks invocations. They can be anything that binary accepts, be it either normal `--benchmark_*` parameters, or some custom parameters your binary takes.
Example output:
```
$ ./compare.py filters ./a.out BM_memcpy BM_copy

```
As you can see, it applies filter to the benchmarks, both when running the benchmark, and before doing the diff. And to make the diff work, the matches are replaced with some common string. Thus, you can compare two different benchmark families within one benchmark binary.
As you can note, the values in `Time` and `CPU` columns are calculated as `(new - old) / |old|`.
3. Compare filter one from benchmark one to filter two from benchmark two:
The program is invoked like:
``` bash
$ compare.py filters <benchmark_baseline> <filter_baseline> <benchmark_contender> <filter_contender> [benchmark options]...
```
Where `<benchmark_baseline>` and `<benchmark_contender>` either specify a benchmark executable file, or a JSON output file. The type of the input file is automatically detected. If a benchmark executable is specified then the benchmark is run to obtain the results. Otherwise the results are simply loaded from the output file.
Where `<filter_baseline>` and `<filter_contender>` are the same regex filters that you would pass to the `[--benchmark_filter=<regex>]` parameter of the benchmark binary.
`[benchmark options]` will be passed to the benchmarks invocations. They can be anything that binary accepts, be it either normal `--benchmark_*` parameters, or some custom parameters your binary takes.

```

```
This is a mix of the previous two modes, two (potentially different) benchmark binaries are run, and a different filter is applied to each one.
As you can note, the values in `Time` and `CPU` columns are calculated as `(new - old) / |old|`.
### U test
If there is a sufficient repetition count of the benchmarks, the tool can do
a [U Test](https://en.wikipedia.org/wiki/Mann%E2%80%93Whitney_U_test), of the
null hypothesis that it is equally likely that a randomly selected value from
one sample will be less than or greater than a randomly selected value from a
second sample.
If the calculated p-value is below this value is lower than the significance
level alpha, then the result is said to be statistically significant and the
null hypothesis is rejected. Which in other words means that the two benchmarks
aren't identical.
**WARNING**: requires **LARGE** (no less than 9) number of repetitions to be
meaningful!
